Well, right now I am in a bit of a bother.  I somehow picked up the win32.polip virus and norton's instructions for removal, not only didn't work but trashed my OS on that machine.  I plan on trying the vertex modeler more often once I get the system back into functional condition.  It takes me a bit longer nowadays to learn new tools.  I had a major medical problem a few years ago involving an aneurysm of the brain and I have had some trouble with math and such ever since.  I can still get there but it seems to take me a bit longer. :)
